Struct NoController 

pub struct NoController;

The default, host/test PowerController that performs no hardware action.

A PowerManager built with PowerManager::new holds a NoController. Its set_power_mode is an explicit, documented no-op that returns Ok(()) — the PowerManager still records the requested mode, so the manager behaves as a software bookkeeping layer, but no clock tree is reprogrammed and no peripheral is gated. Because it reports is_hardware == false, callers that require real transitions can detect its presence via PowerManager::has_hardware_controller or fail loudly with PowerManager::request_mode_strict.

Install a real BSP-provided PowerController with PowerManager::with_controller to get actual power transitions.

Trait Implementations

impl Clone for NoController

fn clone(&self) -> NoController

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for NoController

impl Debug for NoController

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for NoController

fn default() -> NoController

Returns the “default value” for a type.

impl Eq for NoController

impl PartialEq for NoController

fn eq(&self, other: &NoController) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PowerController for NoController

fn set_power_mode(&self, mode: PowerMode) -> Result<()>

No-op: records nothing at the hardware level and reports success so the owning PowerManager can act as a bookkeeping layer. See the type docs for the honesty contract.

fn is_hardware(&self) -> bool

Whether this controller drives real silicon.

fn scale_cpu(&self, mode: PowerMode) -> Result<()>

Optional finer-grained hook: apply only the CPU-frequency scaling for mode (see PowerMode::cpu_freq_factor).

fn gate_peripherals(&self, mode: PowerMode) -> Result<()>

Optional finer-grained hook: gate or ungate peripheral clocks/power for mode.
